dnl	This file is an input file used by the GNU "autoconf" program to
dnl	generate the file "configure", which is run during Tcl installation
dnl	to configure the system for the local environment.

# See the TEA sample extension for description of structure and items.

#-----------------------------------------------------------------------
# __CHANGE__
# This very first macro is used to verify that the configure script can 
# find the sources.  The argument to AC_INIT should be a unique filename
# for this package, and can be a relative path, such as:
#
# AC_INIT(generic/tcl.h)

# Standard compiler checks.

# and runtime Tcl library files in TEA_ADD_TCL_SOURCES.

# and PKG_TCL_SOURCES.

# Windows creates a few extra files that need to be cleaned up.
